Another way of visualizing the construction of the unit 15 is to merely refer to it as a U-shaped clamp which embraces the jawsxlZ which clamp is provided with a hinging tang or shank 20 venient tool or implement accommodating element to expedite operation of said unit I5. Broadly, however, saidunit I5 is merely in-the nature of a hinged lever or armprovided with clamping fingers 23. I 7 The hinging and attaching unit for the clamp unit 15 is denoted by the numeral 25 and is better shown in detail in Figures 7 and 8. Thiscomprises a substantially V-shaped plate 26 which I is fashioned and proportioned to slip into, the correspondingly shaped upper portion of the base II as illustrated in Figure 4. At opposite ends the plate is provided with bendable extensions, there being two pairs of said extensions 21 at one end and relatively short extensions 28 at the opposite end. These are merely bent upon themselves to define hooks which engage over the end portions of the base H to obviate the necessityof using special. bolts or similar fastenings. At the right hand end, the plate is provided with a pair of supplementary extensions 29 whose inner or free ends are bent as indicated at 30 to function as ears which ears serve to accommodate a pintle pin 3| which' serves as a hinge pin for the knuckle 2|; Thus, in a sense, we have an adapter whichis in the form of a plate slipped into the base Hand attached thereto by bendable hooks, said adapter being provided at one end with ears or equivalent elements 30 to accommodate a hinge pin on which the knuckle 2| is pivotally mounted. This provides a simple and economical way of hingedly connecting the clamping unit 20 to the base H.

It is submitted that a two-part attachment of the type herein illustrated and described constitutes a satisfactory and reliable clamp to embrace the jaws l2 and to cooperate therewith in holding the fuse-end I3 securely in place.

It is thought that persons skilled in the art 'and'including a U-shaped member defining a pair of parallel duplicate resilient jaw forming flanges; an adapter unit mounted in the basal portion'of theclipunit, one end of the adapter unit projecting beyond the corresponding end of the clip unit and said projecting end being provided with a hinge pin, a vertical arm hingedly attached to said pin and swingable' toward and from the adjacent'end portion of the clip unit, said arm rising to a point above the upper edges of the flanges and havinga laterally directed portion overlying said flanges andterminatingin an eye to accommodate a tool, saidmarm'being provided with a pair of parallel resilient clamping fingers fashioned to cooperate'with the jaw flanges of said clip unit.
